Use the prependChild() method or the appendChild() method to add a property to the beginning or end of an XML object's list of properties, as the following example shows:

var x1:XML =

Line 1

var x2:XML =

Line 2

var x:XML =
x = x.appendChild(x1);
x = x.appendChild(x2);
x = x.prependChild(

Line 0

);
// x ==

Line 0

Line 1

Line 2

Use the insertChildBefore() method or the insertChildAfter() method to add a property before or after a specified property, as follows:

var x:XML =

Paragraph 1

Paragraph 2

var newNode:XML =

Paragraph 1.5

x = x.insertChildAfter(x.p[0], newNode)
x = x.insertChildBefore(x.p[2],

Paragraph 1.75

)


As the following example shows, you can also use curly brace operators ( { and } ) to pass data by reference (from other variables) when constructing XML objects:

var ids:Array = [121, 122, 123];
var names:Array = [["Murphy","Pat"], ["Thibaut","Jean"], ["Smith","Vijay"]]
var x:XML = new XML("");

for (var i:int = 0; i < 3; i++)
{
var newnode:XML = new XML();
newnode =

{names[i][0]}
{names[i][1]}
;

x = x.appendChild(newnode)
}


You can assign properties and attributes to an XML object by using the = operator, as in the following:

var x:XML =

Smith

x.firstname = "Jean";
x.@id = "239";


This sets the XML object x to the following:


Smith
Jean



You can use the + and += operators to concatenate XMLList objects:

var x1:XML = test1
var x2:XML = test2
var xList:XMLList = x1 + x2;
xList += test3


This sets the XMLList object xList to the following:

test1
test2
test3
